Answer:
Perimeter: 60.6cm
Area: 212.3cm
Step-by-step explanation:
When calulating the perimeter, you are adding the length of all the sides together. Since the figure is a rectangle, two two pairs of sides will be different lengths. Solving is as follows:
P= 11+11+19.3+19.3 or P=11(2)+19.3(2) =60.6
With area, you need the total amount of mass, so you would multiply two sides. In this case, the two are 11cm and 19.3cm.
A= 11(19.3)cm =212.3

Answer:
.45 miles
Step-by-step explanation:
27 mph - How many miles per minute
We already know that there are 60 seconds in an hour. So the best thing to do in this situation is to divide the miles per minute.
27/60 = 0.45
.45 miles per minute
As a fraction, your answer would be 9/20
Answer:
The answer is 3) 40.
Step-by-step explanation:
since you're working with the Pythagorean theorem, you should know that a^2+b^2=c^2, therefore, we know that we only have two sides. we have a and c. we know that a = 42 and c = 58, giving us the equation of 42^2+b^2=58^2,
we want to find b!
so we would simply subtract the two.
58^2 - 42^2 = b
b = 1600
now we want to square root,
b = sqrt1600
which in the end, gives us the answer of 40.
Answer:
x= 50
Step-by-step explanation:
First, simplify the equation
Expand the terms on the left hand side to make it easier to rearrange
-0.2(x-20) =44-x
-0.2x+4 =44-x
Rearrange the equation by moving the numbers to one side and the variables to the other
-0.2x +x= 44-4
0.8x = 40
Isolate for x
x= 40/0.8
x= 50
